WIRE-BARBING MACHINE.

SPECIFICATION forming part of Letters Patent No. 361,928, dated April26, 1887.

Application filed January 10, 1885.

To aZZ whom it may concern.-

Be it known that I, HENRY A. GLOW, a citizen of the United States,residing at Des Moines, in the county of Polk and State of Iowa, haveinvented a new and useful Improvement in NVire-Barbing Machines, ofwhich the following is a specification.

This invention relates to wire-barbing machines; and it consists incertain novel fea tures of construction and combination, hereinafterfully described, and specifically pointed outin the claims.

The invention is illustrated by the accompanying drawings, in whichFigure 1 is a plan View of my improvedwirebarbing machine. Fig. 2 is afront elevation of the same, except shaft D and its bearing d and aportion of the front legs of the machine, which several parts areremoved in this figure in order to more fully exhibit the barbapplyingmechanism. Fig. 3 is an enlarged front view of that portion of thebarb-applying mechanism shown in Fig. 2, but with the bed-plate A brokenaway on the dotted line a: a: of Fig. 1. Fig. 4 is a front elevationshowing that portion of the barb-applying mechanism whichcomes moreimmediately in contact with the barb when the same is being attached tothe fence-wire. This figure also exhibits a staple-barb in position,ready to be secured to the main fence-wire. Fig. 5 is a like viewshowing the barb secured to the main fencewire and the barb-formingdevices in the relative positions which they occupy at the instant thebarb has been completely attached to said main wire. Fig. 6 is avertical longitudinal section of the upright standard 0, showingimmediately adjacent that part of the machine where the barbs areapplied to the main wire. Figs. 7, 8, and 9 illustrate the style of barbfence-wire manufactured on my machine. Fig. 10 is a side elevation ofthe staple-holder K. Fig. 11 is an end View of said holder, looking fromthe right in Fig. 10.

The object of my invention is the construction of a barbing-machineadapted to apply staple-formed barbs to a fence-wire at regularintervals of space along said wire by automatically placingstaple-barbs, one at a time, astride the main fence-wire and holdingthem succes Serial No. 152,454. (No model.)

sively in that position, and pushing the pointed ends of the barb fromthe opposite sides of the main fence-wire past each other and across themain wire in such manner that the barb will completely encircle the mainwire and the points project from said main wire in-opposite directions,or nearly so. I

In Fig. 1, A is a bed-plate, to which is attached the operatingmechanism.

B B are legs employed to support the bedplate.

D is the main driving-shaft, mounted in bearings d d, suspended from thebed-plate.

a. is a pulley rigidly secured to shaft D, and receives thedriving-belt.

D is a shaft situated at right angles to shaft D, and is mounted in abearing, d, secured to one of the legs B. This shaft is driven bymiter-gears a a 1) is a cross-shaft parallel with shaft D, mounted inbearings d 1 which are attached to the front legs of the machine. Onthis shaft are secured a sprocket-wheel, b, and a pinwheel, a". Shaft Dis rotated intermittingly by a cam-wheel, a rigidly secured to shaft D,and arranged to engage the pins in pin-wheel c at each revolution ofshaft D. The pinwheel and shaft D are rotated through an arccorresponding to the pitch of the pin-wheel. Sprocket-wheel I) isemployed to advance the main fencewire through the machine at regularintervals as the barbs are applied and to regulate the spaces betweenthe barbs on said main wire.

0 O C is a standard secured to the top of the bed-plate, that portion,O,which extends upward being provided with a groove in its front face,in which groove thebarbpusher and holder e is held in position andoperated, as hereinafter described. Those portions of the standard G andO which extend laterally along the bed-plate are constructed withgrooves in the front face for the reception of the barbbenders e and c eand e are cams mounted on shaft D directly beneath the barb-pushers,above referred to, e and c and secured to said shaft by splines orfeathers, which prevent the cams from rotating around the shaft, butpermit them to slide lengthwise of the shaft.

f and f are collars rigidly secured to shaft D, and limit the movementof the cams inward or toward the center of the machine.

9 and g are coil-springs,which abut against the outside of the cams cand e", and suitable compression is secured on the springs by thecollars h and 71/, secured to shaft D. These coil-springs are employedto provide elasticity to the sliding barb-benders e and c and therebyadapt the machine to operate upon the varying sizes of wire withoutotherwise changing the adjustment and regulating the movement of thebenders to each particular size of wire.

The barb pushers or benders e and e are operated by the cams e and 6through the studs and rollers l 2 and 3 4, as shown in Fig. 2. Thesestuds are rigidly secured to the barbbenders e and c and extend throughopenings 5 and 6 in the bed-plate.

I is a standard slotted at the top, rising from and secured to thebed-plate.

I is a lever pivoted at one end in the slot above referred to, andhaving its opposite end thrust through an opening in the verticalbarbholder 6, as shown at I, Fig. 2.

1 is a slotted standard suspended from the under side of the bed-plate.

I is a leverhaving one end pivoted in the slot of said standard 1 andhaving the other end connected to the bed-plate bya spring, 1

I is a link,whieh extends from the lever 1 through an opening in thebed-plate to the lever 1*, and is pivoted to each of said levers.

I is a cam-wheel rigidly secured to shaft D, and immediately overlever 1. Cam I and spring P are employed to operate the barbpusher e,the downward movement of said pusher being secured by the pressure ofthe cam upon lever I, and the upward movement by the spring I ,when. thecam has been rotated so as to relieve the lever from pressure.

W is a guide for the main fence-wire.

'75 is a standard rising from the bed-plate and secured thereto, andforms the support for a staple-barb holder, K. This staple-holder isarranged at an angle to the direction of the passage of the mainfence-wire as the latter passes from the guide W through the barbingdevice to the sprocket-wheel Z), and is inclined downward toward thebarb-holder 0, so that the staple-barbs when placed thereon will, bytheir gravity and the jar of the machine when in operation, slide downagainst the holder 6; and when the holder is raised to sufficient heightto permit will slide one at a time under the lower end of said pusher,and will rest against the face of the back of the groove in the standardO, as shown in Figs. 3 and 6. Barbholder K is provided with a slot inthe end nearest the standard 0, which is shown in Figs. 10 and 11. Inthis slot is pivoted a subordinate holder, K", the pivot being at K.

y is a spring secured to the bottom of holder K, and extends up into theslot and in rear of the subordinate holder K, as indicated by dottedlines in Fig. 10. This subordinate holder is arranged to support thestaple-barbs one at a time as they drop down under thelower end of .thebarb-pusher c and to prevent more thag one such barb from dropping offthe holder Ix during each upward and downward stroke of the barb-pushere.

.The barb-benders c and e are constructed with fingers 7 and 8, adaptedto catch the prongs of the barb whether it has been bent into a perfectstaple or not, and shoulders 9 and 10, which press the barb hard againstthe main wire at the moment the barb is attached to the main fence-wire.Barb-bender c is also provided with a thin extension, 6", which projectsbeyond the end of the finger 8 and lies adjacent to the otherbarb-bender, c. The object of this extension is to keep the points ofthe staple-barbs separate from each other, and to prevent them fromimpinging upon each other while they are being pushed in oppositedirections past each other in the act of attaching the barb to the mainwire.

It will be observed that the groove in standard O, in which thebarb-pusherc operates, is inclined at an angle to the barb-benders reand e and to the main fence-wire, and that the barb-support K isarranged at a right angle to the face of said groove. This arrangementallows the staplebarb, when pushed down by the barb-pusher c, to comeastride the main fence-wire \V, with one point or prong on the rear ofthe extension 6 and the other point in front of said extension, as shownin Fig. 4.

S S are guides to direct the staple-barbs in their downward passage fromthe barb-support K to the main wire.

No device is shown for reeling up the barbed wire, no claim being madeto anysuch device, and any well-known method of winding up be ingapplicable to this machine.

From the description given in detail of the function of the severalparts of my machine the operation of the entire machine will beperfectly plain.

Having now fully described my invention, what I claim as new, and desireto secure by Letters Patent, is-
